ARM Holdings climbs after earnings report

European stock markets moved sharply higher for a second straight day on Tuesday on the back of some well-received corporate updates, shaking off jitters about Greece.

Investors were waiting for the closely watched German ZEW economic sentiment survey to be released later in the morning.

The Stoxx Europe 600 index rallied 1.2% to 411.89, building on a 0.8% gain from Monday. Most European benchmarks kicked off the week on a strong footing, boosted by China's move to stimulate the economy and largely ignoring concerns about Greece's slow progress in renegotiating a reform program with its lenders.

Greek woes: Greece needs to agree on a range of economic overhauls with the lenders in order to receive the next much-needed tranche of bailout and avoid running out of cash. On Monday, Athens ordered public entities including state-owned companies and public pension funds to transfer cash reserves to the central bank (http://www.marketwatch.com/story/greece-orders-public-bodies-to-transfer-cash-to-central-bank-2015-04-20), a move that comes as Greece scrambles with finding money it needs to service debt.

The Eurogroup of eurozone finance ministers meets on Friday to discuss the Greek bailout, but few expect a major breakthrough in talks. A top EU official has given Greece a deadline of the Eurogroup meeting on May 11 (http://www.marketwatch.com/story/top-eu-official-to-greece-agree-to-reform-by-may-11-or-else-2015-04-17) to agree on a reform plan or potentially face a default.

Greece's Athex Composite index lost 1.1% to 720.75 on Tuesday.

Other markets: Germany's DAX 30 index moved back above the 12,000 mark, trading 1.4% higher at 12,057.52.

France's CAC 40 index gained 1% to 5,238.25, while the U.K.'s FTSE 100 index added 0.6% to 7,091.78.

Data: On a quiet data day, the highlight is Germany's ZEW index for April, due at 10 a.m. London time, or 5 a.m. Eastern Time. Analysts at Société Générale expect a decline to 49.6 in economic sentiment after five straight months of increases.

"This follows an already weaker than expected outcome of 54.8 in March, as the positive news flow has been petering out somewhat and more realistic expectations of growth set in after a stellar Q1," they said in a note.
